GSM Vs. CDMA: Which SIM Card Technology Does Straight Talk Use?

GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access) are two different technologies used by mobile networks. It’s important to know which technology a service provider uses before purchasing a SIM card.

For Straight Talk users, the type of SIM card technology used depends on the network the customer’s phone is compatible with. Straight Talk operates on both GSM and CDMA networks, so it’s crucial to determine which one is compatible with your device.

GSM SIM cards are compatible with phones that support GSM technology. These cards use a removable SIM card chip and require unlocked GSM-compatible phones. Straight Talk’s GSM network uses T-Mobile and AT&T towers, offering widespread coverage nationwide.
